1. Introduction
The SCSI-Fibre Channel Router (SCSI-FC Router) is a simple to maintain stand-alone SCSI extender.
By converting SCSI to Fibre Channel, it can provide lengths of 30m (98 ft) to 10 km (6.2 miles)
depending on the fiber optic cable used.
Figure 1-1. SCSI-FC Router
To the host, the SCSI-FC Router is transparent and the device on the Fibre Channel loop appears as a SCSI
device. Since the SCSI-FC Router appears to the host as a parallel SCSI device, its usage and installation are
very simple. The SCSI-FC Router attaches directly to the SCSI host adapter. The SCSI-FC Router is supplied
in a self-contained 3"(H) x 4.25"(W) x 11"(D) enclosure that can either be installed on a desktop or four-
abreast in the 19" rackmountable Hub Enclosure. For more information concerning the SCSI-FC Router Hub
Enclosure, refer to the
Hub Enclosure Installation Guide .
1.1. System Requirements
•Fibre optic cable: 62 or 50 micron fibre optic cable with dual SC connector, or
Copper cable: Twinax cable with DB-9 or HSSDC Gigabit Interface Converters (GBIC)
•SCSI-FC Router (host) microcode revision 7.60 or later
•SCSI-FC Router (device) microcode revision 2.50 or later
•SCSI-2 HVD compliant host adapter
•SCSI-2 compliant host
•SCSI-2 compliant cabling
•Proper AC (alternating current) electrical power source.
1.2. SCSI-FC Router Defined
There are two SCSI-FC Routers in a single Fibre Channel loop. To prevent confusion, the following
diagram defines the various SCSI-FC Routers by their positions within the loop. The SCSI-FC
Router directly attached to the host or the server is the ’host router’ and the SCSI-FC Router directly
connected to the SCSI devices (disk or tape drives) is the ’device router’.

3.2. SCSI-FC Router Mode Switches (SW2)
The SCSI-FC Router mode is selected by utilizing the DIP switches in SW2 (for SW2’s location, see
Figure 3-2). The SCSI-FC Router power must be cycled to effect a change in mode. The first four DIP
switches are independent of the other DIP switches on switch 2 (SW2).
•DIP switch 4 and 5 are independent of all other DIP switches on SW2 and activate the
Connection Check or the Subsystem Device Check. And when activated simultaneously they
clear the node mapping table.
•DIP switch 6 is not used at this point.

Host Mode
This is the normal operating mode of the host SCSI-FC Router. Two host routers can not exist
simultaneously on the same serial loop.
3.2.2. Microcode Revision Mode
In this mode, the SCSI-FC Router microcode revision level will be presented as a status code on
the Status LED. The microcode revision is a three digit number. A decimal separates the first digit
from the second.
Example: Revision number 7.60
To run the Microcode Revision mode follow the steps below:
1. Power off the SCSI-FC Router.
2. If user is checking the host router microcode, SW2 must be placed in the host mode and
if user is checking the device router microcode, SW2 must be placed in the device mode.
3. Power on the SCSI-FC Router.
4. Watch the blinking pattern of the Status LED (see section 3.1.4 to decipher the LED readout).
5. After revision level is determined, power off the router, return it to its proper operating
mode and power it on.
3.2.3. Connection Check Mode
In this mode, the host router will perform a test to ensure that communication to the device
router is operating correctly. If communication can not be established or if a high number of
errors are reported then the test will fail.
3.2.4. Subsystem Device Check Mode
In this mode, the SCSI-FC Router will talk to the SCSI device(s) (disk or tape drives) attached
to the device router ensuring that proper communication is established.

4.2. Checking Cables and Connections
1. Be sure to power off the device(s) to which the connector is connected before removing it.
2. Visually study the end of both connectors on the cable. Ensure that pins are not broken, bent
or pushed in.
3. If a connector is damaged, replace connector and power on the device(s).
4. Ensure that the connector is securely fastened to the device(s). A loose connection can
cause termination problems.
5. Ensure the cable length does not exceed HP’s recommended length (see section 4.1.1 or 4.1.3)
6. If problem still exist, power off the device(s) and replace the cable.
4.3. Power LED Not Lit
This indicates that there is no power to the SCSI-FC Router.
1. Ensure an AC plug is connected to a working wall outlet and the other end is connected to
the SCSI-FC Router unit.
2. Ensure the power switch is in the on position (1 represents on and 0 represents off).
•See Figure 3-2. Rear of SCSI-FC Router for power switch location.
3. If LED is still not lit then turn off unit and replace the power cable.
4. If LED is still not lit then recycle the SCSI-FC Router’s power.
5. If LED is still not lit then replace the SCSI-FC Router unit.
•Go to section 4.4 Replace a SCSI-FC Router.
6. After replacing the unit and the problems persist, contact your SCSI-FC Router vendor.
4.4. Replace a SCSI-FC Router
1. Power off the SCSI-FC Router being replaced and the SCSI-FC Router that will replace it.
2. Set switch one and two (SW1 and SW2) on the new SCSI-FC Router to match the switch settings
on the (old) SCSI-FC Router that is being replaced.
3. Swap each of the old connections from the replacement (old) SCSI-FC Router to the new SCSI-
FC Router. Ensure that all cables and connector are securely fastened.
4. Power on the new SCSI-FC Router.
5. After the LEDs have finished blinking, the power LED (green) and status LED (green) should be solid
on and the fault LED (yellow) should be off.
•To locate the LED's location, see Figure 3-1. LED Location for Front Panel.
6. Replacement of the SCSI-FC Router is complete.
7. After replacing the unit and the problems persist, contact your SCSI-FC Router vendor.
